Moisture Issues In Master Bathroom
Comments (4)Let me preface this by saying I am by no means an expert, I just know from experience and things I have read. Yes, you really must have an exhaust fan. There are also probably other moisture problems you can't see due to there being no fan - but for your sake hopefully nothing major. It definitely should vent outside the house - you either have to cut a hole in the gable of your house or through the roof, or, if you must, in the soffit. Venting though the roof I *think* is the best way, but also the most difficult to do correctly. They make all the pieces for whatever you need depending on where the vent will be. We have one in my house that had to be vented to the soffit, and we have a little circular grill/vent cap that only opens when air comes out of it. I'll link a similar product. As for who should do it - if you're handy you could probably DIY (I believe there is a video on how to do the gable version on this old house), otherwise probably a roofing/attic insulation type contractor would be good.

Comments (15)Hopefully your ductwork is in good condition and properly sized. The fan should be sized for the bathroom. Here are some guidelines: Small rooms: For bathrooms up to 100 square feet in area, HVI (Home Ventilation Institute) recommends that an exhaust fan provide 1 CFM per square foot (approximately eight air changes per hour) to properly ventilate the bathroom. Example: Bathroom is 8'x5' (with 8' ceilings). Multiply 8 x 5 = 40ft. Bathroom area is 40ft. At 1 cfm per square foot the minimum recommendation is a fan rated at 40 cfm. Larger rooms: For bathrooms above 100 square feet in area, HVI recommends a ventilation rate based on the number and type of fixtures present, according to the following table: Toilet 50 CFM Shower 50 CFM Bath Tub 50 CFM Jetted Tub 100 CFM Duration of ventilation: HVI recommends that the fan be left on for 20 minutes after use of the bathroom. A timer is a good solution, allowing the fan to turn off automatically at the proper time. One thing you should know is most fans only produce 50% of the rated cfm because of undersized and poorly installed ducts. Ducts should be hard pipe, not corrugated plastic that will cause too much restriction and possibly degrade and leak over time. 37 year veteran HVAC professional Here is a link that might be useful: Heating, Ventilation and Air Conditioning Help and Advice...See MoreBathroom Vinylboard
Comments (2)I think it's tileboard or sometimes called wallboard that you are thinking of. If you got the money and the help I would put up the tileboard which comes in many prints not just fake ceramic tile. Like everything else the tileboard becomes dated after a few years so you might think about going with something classic that will go for years. Are you using your exhaust fan in bathroom letting it run for about 20 mins after showering is supposed to be a huge help with moisture problem in bathrooms. Also when was the last time that exhaust fan was replaced or had a good cleaning an oiling? A slow dirty fan can really cut down on the moisture removal....See Morepainting bathroom with black 'chalkboard' paint-ok for moisture?
Comments (5)thanks grandma...after reading palimpsests next post, I guess I am agreeing with you! palimpsest-I like the idea of high gloss, but our walls have a lot of imperfections. The idea for black came to me because we do plan on TOTALLY redoing it in a few years...tile, sinks,cabinets...bumping out the shower to make it bigger...a really big project. So, I was willing to go "funky" in the meantime. I did a ralph lauren metallic in the second bathroom...a shark colored silver...and it looks like cr@p due to all the imperfections on the walls! Made me sad...my DH does all the work around the house...this was *my* little project that I wanted to surprise him with... I picked the paint myself without consulting him, did the painting myself..it was a mistake! He chuckles at me every time he sees those walls! I will rethink the chalkboard paint. I just have a can sitting here and I want to use it. BUT...that's not enough reason to do it. Thanks again!...See Morewoodbutcher_ca
